In which the liberties of reason and choice granted by divine Providence are extolled as the foundation of virtue, and the futility of attempting to eradicate sin by mere prohibition of its outward matter is demonstrated with measured reflection. The encumbrances and discouragements imposed by a strict licencing order upon learned men and the free exercise of truth are lamented as both a dishonour to authors and a perilous restraint upon the flourishing of knowledge, forewarning that such a yoke may breed a servitude more grievous than that overcome.

In which the origins and nature of book-licensing are examined with a discerning eye, revealing it as a foreign and tyrannical imposition rather than a beneficent law of well-ordered states, and the exercise of reading is extolled as a necessary engagement with both good and evil for the cultivation of true virtue. The discourse further contemplates the impracticality and futility of controlling all human pleasures and pastimes by licensure, advocating instead for temperance, wise education, and moral persuasion as the true bulwarks against corruption.

In which the author earnestly addresses the Parliament of England, extolling the virtues of civil liberty and the free exchange of ideas while cautioning against the overreach of licensing that stifles learning and truth. He thoughtfully examines the history of book censorship across ancient and Christian societies, revealing the perils of suppressing knowledge and urging a temperate vigilance rather than harsh restraint, lest reason itself be slain.
